My studio/classroom space holds a plethora of materials so nobody went wanting.
"That didn't work..." and then "This keeps falling off ..." is what I hear in the classroom studio. However, I think kids can be more accommodating if Plan A or B doesn't work. There are always Plans C - Z. Never having gone down this art road before can be an asset to younger people.
Of course, my overflowing bins and colorful "drawers of potential" helped, too.
